Laser bioprinted hair follicle could produce hair for product testing

L'Oréal (Clichy, France) is partnering with Poietis (Pessac, France), a biotechnology firm with the ambition of producing 3D laser-assisted bioprinted hair follicles that will grow hair for product testing. L'Oréal (Clichy, France) and biotechnology company Poietis (Pessac, France) have signed a multi-year research partnership to work on creating an in vitro 3D bioprinted hair follicle that would be used to produce hair for product testing. Poietis uses laser-assisted bioprinting – successively layering microdrops of bioinks with a laser beam scan – to produce biological tissue in high cellular resolution (on the order of 10 μm) and with significant cellular viability...
